Product details
Overview
TLC084AIPWP from Texas Instruments is a quad-channel BiMOS operational amplifier optimized for single-supply operation across 4.5 V to 16 V, delivering 10 MHz bandwidth, ±57 mA output drive, and 16 V/µs positive slew rate. It serves as a high-output-drive upgrade for TL08x users in audio line drivers, sensor signal conditioning, and industrial analog front-ends requiring rail-to-rail input (VICR = GND to VDD–2 V) and robust load driving.
For engineers reviewing the TLC084AIPWP datasheet, TLC084AIPWP pinout, TLC084AIPWP application, or TLC084AIPWP equivalent, key selection criteria include guaranteed 2000 µV max input offset voltage (A-grade), 125 µA/channel shutdown current, TSSOP-20 package thermal performance (θJA = 26.1°C/W), and channel independence in high-speed multi-channel systems.
Technical Context
The TLC084AIPWP integrates a low-noise CMOS front end with a high-current bipolar output stage, enabling simultaneous high input impedance (>1 GΩ differential resistance), low input noise (8.5 nV/√Hz at 1 kHz), and ±50 mA load capability. Its architecture supports stable unity-gain operation with phase margin ≥32° into 50 pF loads.
Designed for single-supply systems, it features ground-sensing common-mode input range, internal offset nulling compatibility via external resistors, and independent shutdown control per pair of channels (pins 5 & 10). No internal compensation is required for gains ≥1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - Enables stable closed-loop operation up to 100 kHz with 100× gain margin. |
| Output Drive | ±57 mA - Drives 600 Ω loads directly without external buffers in line-level audio or DAC output stages. |
| Slew Rate | +16 V/µs / –19 V/µs - Supports fast transient response in pulse amplification and active filter applications. |
| Input Offset Voltage | 2000 µV max (A-grade, –40°C to 125°C) - Ensures <0.1% error in 2 V full-scale precision sensor interfaces. |
| Supply Range | 4.5 V to 16 V - Operates from single Li-ion battery (4.2 V) up to industrial 12 V rails without level-shifting. |
| Shutdown Current | 125 µA/channel - Reduces system standby power by >93% vs active mode (1.9 mA/channel) in portable instrumentation. |
| Input Noise | 8.5 nV/√Hz @ 1 kHz - Maintains SNR >90 dB in 20 kHz audio band with 10 kΩ source impedance. |
Pinout & Package
TLC084AIPWP uses a thermally enhanced 20-pin TSSOP (PWP) package with exposed thermal pad, rated for 4.79 W power dissipation (θJA = 26.1°C/W) and suitable for high-density PCB layouts requiring efficient heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 12, 14 | Inverting Input (1IN–, 2IN–, 3IN–, 4IN–) | Differential inputs accepting signals down to GND; require matched trace routing for crosstalk control. |
| 2, 4, 11, 13 | Non-inverting Input (1IN+, 2IN+, 3IN+, 4IN+) | High-impedance CMOS inputs; bias currents <100 pA enable high-Z sensor interfacing. |
| 5, 10 | Channel Pair Shutdown (1/2SHDN, 3/4SHDN) | Active-low logic inputs; pull ≥2 V above GND to enable, ≤0.8 V to disable corresponding amplifier pair. |
| 6, 15 | Positive Supply (VDD) | Single supply rail; decoupling capacitor (0.1 µF) required within 5 mm of each pin for stability. |
| 7, 16 | Ground (GND) | Analog reference return; connect to solid ground plane under thermal pad for optimal thermal and noise performance. |
| 8, 9, 17, 18 | Outputs (1OUT, 2OUT, 3OUT, 4OUT) | Class-AB bipolar outputs capable of sourcing/sinking 57/55 mA; tolerate capacitive loads ≤100 pF unconditionally. |
| 19, 20 | No Connect (NC) | Unbonded pins; must remain floating-no routing or solder mask openings permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range support | Operates from 4.5 V (single-cell Li-ion) to 16 V (industrial bus), eliminating need for LDO pre-regulation. |
| Ground-sensing input stage | VICR includes GND, enabling direct interfacing with 0–3.3 V microcontroller ADC references or bridge sensors. |
| Thermally optimized package | PWP's 1.40°C/W θJC enables 4-channel operation at 12 V/50 mA without heatsink in 70°C ambient. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464AIPW | Lower bandwidth (6.4 MHz), lower output drive (±35 mA), rail-to-rail output only (not input). | Better suited for low-power, low-voltage (2.7–6 V) portable designs where full 16 V swing is unnecessary. | Select when supply is ≤6 V and output loading <35 mA; avoid for 12 V industrial drivers or ground-referenced sensors. |
| OPA4340UA | Rail-to-rail I/O, lower noise (8 nV/√Hz), but limited output drive (±20 mA) and narrower supply (2.7–5.5 V). | Optimized for precision, low-noise, low-voltage data acquisition-not for high-current line driving. | Choose for battery-powered medical sensors or portable test equipment needing ultra-low distortion below 100 kHz. |
Compared with TLV2464AIPW and OPA4340UA, the TLC084AIPWP uniquely combines 10 MHz bandwidth, ±57 mA drive, and ground-sensing inputs in a single 20-pin TSSOP, making it the only option among the three capable of driving 600 Ω audio loads from 12 V rails while maintaining DC precision over extended temperature.

FAQ
What is the maximum operating temperature range for the TLC084AIPWP?
The TLC084AIPWP is specified for operation from –40°C to +125°C (I-suffix grade), validated across this full range for parameters including input offset voltage (2000 µV max), supply current (3.5 mA max per channel), and output drive (±55 mA min). This makes TLC084AIPWP suitable for under-hood automotive and industrial control environments where ambient temperatures exceed 85°C.
Does the TLC084AIPWP support true rail-to-rail input operation?
The TLC084AIPWP supports common-mode input voltage from GND to VDD–2 V, enabling ground-referenced signal acquisition but not full rail-to-rail input. For example, at VDD = 12 V, VICR spans 0 V to 10 V. This differs from rail-to-rail input op-amps that accept inputs within 50 mV of either rail. The TLC084AIPWP's input stage is optimized for single-supply precision with guaranteed operation at GND.
How does the shutdown function work on the TLC084AIPWP?
The TLC084AIPWP features two independent shutdown inputs: pin 5 (1/2SHDN) disables channels 1 and 2, and pin 10 (3/4SHDN) disables channels 3 and 4. Each is active-low: applying ≤0.8 V places the corresponding pair in ultralow-power state (125 µA/channel), while ≥2 V enables normal operation. The shutdown transition times are 0.47 µs (turn-on) and 2.5 µs (turn-off) at VDD = 12 V, as measured to 50% of final supply current.
Can the TLC084AIPWP drive capacitive loads without oscillation?
Yes, the TLC084AIPWP is stable driving up to 50 pF capacitive loads with 10 kΩ series resistance (phase margin ≥32°), and remains unconditionally stable up to 100 pF when a 10 Ω isolation resistor is added in series with the output. This capability allows direct connection to ADC input capacitors, long cables, or LCD bias networks without external compensation components-verified in TI's SLOS254F datasheet Figure 19–20.
What is the thermal performance advantage of the PWP package used in TLC084AIPWP?
The TLC084AIPWP's PWP (TSSOP-20 with PowerPAD) package delivers θJA = 26.1°C/W and θJC = 1.40°C/W, enabling 4.79 W maximum power dissipation-over 4× higher than standard SOIC-14 packages. When mounted on a 2-layer PCB with 1-in² copper pour under the thermal pad, TLC084AIPWP maintains junction temperature <115°C at full 12 V/50 mA per channel output, critical for sustained operation in enclosed industrial enclosures.
